摘要: The cyclotron resonance of thermally excited free holes has been observed in synthetic semiconducting diamond at ultrahigh magnetic fields up to 150 T generated by the single-turn-coil technique with pulsed far-infrared laser radiations 28, 36, and 119 μm. Three absorption peaks were above room temperature for parallel , crystallographic directions. typical value ω c t was as small 2 40 o C even fields. One three cyclotron-resonance inactive circular polarization holes, while other two lines active
